Agilent 34401A Service Guide.pdfIEC Measurement Category II includes electrical devices connected to mains at an outlet on a branch circuit. Such devices include most small appliances, test equipment, and other devices that plug into a branch outlet or socket. The 34401A may be used to make measurements with the HI and LO inputs connected to mains in such devices, or to the branch outlet itself (up to 300 VAC). However, the 34401A may not be used with its HI and LO inputs connected to mains in permanently installed electrical devices such as the main circuit-breaker panel, sub-panel disconnect boxes, or permanently wired motors. Such devices and circuits are subject to overvoltages that may exceed the protection limits of the 34401A. Note: Voltages above 300 VAC may be measured only in circuits that are isolated from mains. However, transient overvoltages are also present on circuits that are isolated from mains. The Agilent 34401A are designed to safely withstand occasional transient overvoltages up to 2500 Vpk. Do not use this equipment to measure circuits where transient overvoltages could exceed this level.

本系統(tǒng)采用電動(dòng)機(jī)電樞供電回路串接采樣電阻的方式來(lái)實(shí)現(xiàn)對(duì)小型直流有刷電動(dòng)機(jī)的轉(zhuǎn)速測(cè)量。該系統(tǒng)主要由二階低通濾波電路,小信號(hào)放大電路、單片機(jī)測(cè)量顯示電路、開關(guān)穩(wěn)壓電源電路等組成。同時(shí)自制電機(jī)測(cè)速裝置,用高頻磁環(huán)作為載體,用線圈繞制磁環(huán),利用電磁感應(yīng)原理檢測(cè)電機(jī)運(yùn)行時(shí)的漏磁,將變化的磁場(chǎng)信號(hào)轉(zhuǎn)化為磁環(huán)上的感應(yīng)電流。用信號(hào)處理單元電路將微弱電信號(hào)轉(zhuǎn)化為脈沖信號(hào),送由單片機(jī)檢測(cè),從而達(dá)到準(zhǔn)確測(cè)量電機(jī)的速度的要求。In this system, the sampling resistance of armature power supply circuit is connected in series to measure the speed of small DC brush motor. The system is mainly composed of second-order low-pass filter circuit, small signal amplifier circuit, single-chip measurement and display circuit, switching regulated power supply circuit and so on. At the same time, the self-made motor speed measuring device uses high frequency magnetic ring as the carrier, coil winding magnetic ring, and electromagnetic induction principle to detect the leakage of magnetic field during the operation of the motor, which converts the changed magnetic field signal into the induced current on the magnetic ring. The weak electric signal is transformed into pulse signal by signal processing unit circuit, which is sent to single chip computer for detection, so as to meet the requirement of accurate measurement of motor speed.

因此，您想編寫一個(gè)內(nèi)核模塊。您知道C，您已經(jīng)編寫了一些可以作為進(jìn)程運(yùn)行的常規(guī)程序，現(xiàn)在您想知道真正的動(dòng)作在哪里，一個(gè)通配指針可以擦掉文件系統(tǒng)，核心轉(zhuǎn)儲(chǔ)意味著重新啟動(dòng)。內(nèi)核模塊到底是什么？模塊是可以根據(jù)需要加載和卸載的代碼段。它們擴(kuò)展了內(nèi)核的功能，而無(wú)需重新引導(dǎo)系統(tǒng)。例如。模塊驅(qū)動(dòng)程序的一種類型是設(shè)備驅(qū)動(dòng)程序，它允許內(nèi)核訪問沒有模塊的系統(tǒng)硬件，我們將不得不構(gòu)建單片內(nèi)核并將新功能直接添加到內(nèi)核映像中，除了具有更大的內(nèi)核之外，這還具有缺點(diǎn)每次我們想要新功能時(shí)都要求我們重建并重新啟動(dòng)內(nèi)核的過程So, you want to write a kernel module. You know C, you, ve written a few normal programs to run as processes, and now you want to get to where the real action is, to where a single wild pointer can wipe out your file system and a core dump means a reboot.What exactly is a kernel module? Modules are pieces of code that can be loaded and unloaded into th upon demand. They extend the functionality of the kernel without the need to reboot the system. For example.one type of module is the device driver, which allows the kernel to access hardware connected to the syste without modules, we would have to build monolithic kernels and add new functionality directly into the em ernel image, Besides having larger kernels
